Drones | The complete flight dynamics

No music in the background. Perfect video! Thank you!

[@danyvarna5094]

The most important part of a drone is its sensors and electronics package. If this is good enough you can use all kinds of motors and inefficient blades to produce results as far as power exceeds weight.

[@carboncopters5674]

Dany Varna Each part is important. In many cases lift can exceed weight but the craft might still be impossible to tune / fly correctly cause mechanical factors like stiffness, center of gravity position and many others.

[@danyvarna5094]

@@carboncopters5674 , turn your brain on. All of what you mentioned is either performance related or correctable to a satisfactory level by the electronic suite. Every part od important bit some are decisive, thus you start with them as a choke point.

[@carboncopters5674]

Dany Varna No its not. Electronics cannot change the laws of physics. Its entirely possible to make UAV impossible to fly in a controlable manner not to mention ,,satifactionary” level if for example the center of gravity is too far away or some elemnts of the craft interfere with air stream. You obviously have no experience in building crafts of this type or especially the experimental ones if you deny the obvious significance of mechanical contruction.

[@danyvarna5094]

@@carboncopters5674 , you seem to know little. Let me help you. Do you understand that most current military flying machines that we use are either not aerodynamic or have been planned with a level of aerodynamic instability? :-) Read, man. I am building drones so I know what I am taking about. With enough power and a good electronics-sensors module you can make a brik fly. Chech the development of quadcopters and compare it with the timeframe of the rise of cheep electronics.

[@carboncopters5674]

Dany Varna Aeroplanes are built instable statically on purpose and it is a well planned and calculated process. Its not ,,do whatever and it will fly”. This actually the proof of significance of the airframe design itself and using the advantage which electronics gives. The fact that you ,,build drones” doesn't make you be anyone who can ,,explain things” especially to people who design stuff you probably buy and stick together according to manual and tutorials. If you want to prove your point about electronics does it all, please show me bi-copter or tri-copter that flies in a satisfaction ally way withtout flaws of these configuration, of course self designed frame. You are ,,pro''' after all.

[@icetea4345]

As a drone operator I can say that you have to add yaw to fly a circle or to make simple turn etc.. Besides when the drone is hovering, the motors are not necessarily rotating at the exact same speed (due weight distribution, wind) the gyro's inside fight controller of the drone regulates the motor speed of each motor in order to stay level. For example, if you add more weight on one motor arm, that arm will spin faster to stay horizontal.

[@albertvaldez2669]

As a pilot, I approve this comment! 👍

[@LucDutra92]

Yeah I learned that pretty quick piloting mine. If done as described here, the drone will just fly in a diagonal angle

[@grim-upnorth]

The drone will not turn in a circle if you just pitch and roll it. it will move diagonally. you will need to induce some yaw in order to constantly adjust the drone's heading.

[@fabricer.9426]

Definitely! 👍

[@floridaaerialmedia]

You are correct!

[@humble2246]

Yep, -dji mini 2 owner

[@ugursoydan8187]

If you do the roll and pitch at the same time, you're right. But if you do the pitch firstly and if you do the roll after the drone gains a certain amount of velocity,it will do a circular motion

[@ethanpennington247]

of course

[@rituraj8615]

I came to know about the existence of quadcopter during my school days from the movie "3 idiots" and today I learnt the principle behind this. Thankyou for making this video. Kindly make a video on solar powered drones.

[@rashisinghsingh7461]

Haha hhaaaa

[@nishatiwari9212]

Are u in FIITJEE ritu raj??

[@nishatiwari9212]

South Delhi??

[@Qwarzz]

If you pitch and roll, wouldn't you just go in a diagonal direction. So not going in a circle but still in a straight line. To go in a circle you'd have to yaw as well and it gets quite complicated at that point.

[@arihantjain1662]

Well the logic that I could think is since circular motion is a 2d motion and requires force in 2 directions only thus only pitch and roll is required. If we apply yaw also then it will be a spherical motion instead of a circular one. I may be wrong but this is only possible explanation I can think of.

[@pi314ever]

There's a coupling between roll and yaw. Typically, it's way more efficient to roll to change direction than yaw.

[@akh345]

You are correct. It is equivalent to "strafing" in video games. Both pitching and rolling preserves the direction that the quadcopter is facing.

[@codebender9435]

this

[@thomasa.7759]

yea, but you would go in a circle, but the front will not we straight as shown. You would need yaw and roll to do a circle like is shown

Good class sir about the drones thank you very much you are lifting the knowledge of students which we can't learn in our colleges I will support you sir

[@venomousmedic]

he must have used a lot of lift force ;)

[@franeentertainment3915]

I loved it ,people like you can change the world

[@CactusJackSlade]

Great visual... my only comment (correction?) would be that yes, different motor speeds (torque) on the diagonal motors causes yaw. To pitch or roll you are increasing the motor speed in either the front/rear or right/left motors to provide more or less lift to make it change it's attitude, not torque. Please correct me if I am wrong?

[@ketso-l7b]

One thing you should ask yourself is what is torque? A force that causes rotation. when you change the motor speed,the blades creates more lift which provides torque to that side of the drone.

[@mrssonikuri]

Wow this actually made sense Thank youuu Really appreciate it

[@handiman5]

[@mesaber86]

6:17 This is not how my DJI Phantom 4 works. Stick forward = goes forward, stick right = goes right, stick forward+right = goes diagonally. No circle for me without Yaw. I would like this changed though if someone knows how.

[@plasmachicken]

Yeah that's indeed wrong in the Viedo

[@mesaber86]

@mr.1n5an_e well yes. Looks very unnatural but yes.

[@samyakulis]

The video explains ACRO mode….you are operating in ATTI mode.

[@ianbudgetrc2574]

@4:52 that can only stay hovering like that if all 4 propellers are angled parallel to the ground and are rotating at the same speed, given that the lift is equal to the total weight of the drone. And also if there's no wind movement

[@fullfoolfu7944]

You guys are freaking awesome!

[@sandwipdas8858]

Thanks a lot for this great video.

[@Johny40Se7en]

Really nice visualiser and explanation. Got a question - why not add four blades to each propeller instead of two, wouldn't it use less energy to get the same amount of lift force?

[@CJ.1998X.Y.Z]

No due to the increase in drag

Car drag is the application of Stokes theorem when the car reaches its terminal velocity it can no longer accelerate forward but attains a max constant acceleration which just ewuals the opposing drag viscous force.

Thanks for all the great information… If you have time could you explain how, given the physics of the airfoil, an airplane can fly upside down? Logic would dictate the inverted “lift” would pull the plane to the ground...

[@nadeem722]

2:58 Doubt 🖐, propeller blade is designed in such a way that when it rotate in One Direction, then they will push the air downward to create a lift. In this case if the two out of four sets of propeller rotate in counter clock wise, will they create upside down force?

[@adamtraynor3922]

No, because the blades are designed opposite to the other blades, thus it creates downward force.

Hey thanks for the info at 6:04. I'm trying to code in Unity to use physics forces to rotate objects around a certain point just like what was shown. That helps me realize that the solution is much more simple than I thought. Cheers!

[@CannabisTechLife]

@Hussain Mehemud Kusum Yeah C#. I'm a Technical Artist for game development. The comment was in response to a personal project i'm working on where i'm driving the transform vector position based off of physics instead of forced script calculations .

[@C204unit]

A little correction that does not remove anything from the educational value of the video. By convention, torque is a vector that is directed upward the vertical axis for anticlockwise spin and downward for the clockwise spin. If the angular speed of the rotation of the rotors is constant then the torque is zero. I would rather talk about angular momentum since it is related both to the angular speed and the rotational inertia of the body. Edit: On second thought you are fine using just the concept of torque because in the real work the friction force of the rotating parts of the electric motors can be overcome by an opposite force that would be the torque. So even for a constant angular speed of the rotor, to overcome the friction force of the axle of the rotor and the drag force of the blades a constant positive torque is required. Peace
